In this paper, the standard potential of micro-solubility salt electrode is calculated by different methods, which shows that the contribution of micro-solubility salt to the standard electrode potential includes two parts.
通过对微溶盐标准电极电势求解例题的演算,说明微溶盐作电极对电极电势的贡献是分步进行的,一是微溶盐的解离,二是金属离子的还原反应。
The is lower than standard electrode potentials of alkali metal elements in the same family;contrarily,the of beryllium and lithium is situated in the same period and is higher than standard electrode potentials of alkaline-earth elements.
锂的标准电极电势 较同族碱金属元素低;相反地,与锂处于同一周期的元素铍的标准电极电势 却较同族碱土金属元素高,二者呈现不规则性。
The relation between standard electrode potential of insoluble salt electrode and insoluble salt K sp has been discussed, and the relation formula of them has been determined.
从两个不同的角度对难溶盐电极标准电极电势与其活度积常数Ksp之间的关系作了讨论,确立了难溶盐电极的标准电极电势与Ksp之间的关系
A calculation method of standard electrode potentials in the complex system of the aqueous solution was derived in this paper.
推导了水溶液中复杂体系的标准电极电位计算公式,用此公式计算了目前国际上使用的一些标准电极电位,并对现有标准电极电位的数据作了分析。
Comparing it with the standard electrode potential of nitric acid,the reason of dissolution of HgS in aqua regia was quantitatively revealed,and this is that the high concentration of chloride ions reduces the reduction potential of sulfur in HgS,thus raising the reducing power of HgS rather than that the oxidizing power.
根据热力学平衡原理和设计的可逆电池反应,由 E~0(Hg~(2+)+S/HgS)数据,计算了 E~0(HgCl_4~(2+)+S/HgS+4Cl~-)数值,将其与 HNO_3的标准电极电位比较,定量地揭示了 HgS 溶于王水的原因在于该溶液中高浓度 Cl~-离子降低了 HgS 中硫的还原电位,从而提高了 HgS 的还原性所致,并非王水的氧化性比 HNO_3的更强。
